What is supraspinatus muscle?

Supraspinatus muscle is a shoulder muscle that connects the scoop or shoulder blade with the bone of the upper arm, humerus. This muscle is involved in the abduction of the arm, which means lifting the arm up and away from the body. It also acts with other muscles as part of a group of muscles and tendons known as a rotator cuff to withstand gravitational force and stabilize the shoulder. For example, it helps to maintain the position of the arm after ejecting the object.

Structurally, the original muscle tendon supraspinatus is attached to the upper part of the shoulder blade. Above the spine of the shoulder blade is a shallow cavity, and this is a place where the origin of the muscle. The tendon then passes through the bony extension of the shoulder blade called the acromion process, which forms a partial tunnel at the top of the arm. After emerging from the acromion process at the top of the arm, the muscle is attached by its insertion of the tendon into the point at the top of Thumerus.

4 It is assumed that a relatively small muscle that acts as an assistant of deltooid, stabilizeE joint and provides some strength, while most of the energy needed for the kidnapping movement is supplied by a larger deltooid muscle. Supraspinatus is the most active during the first 30 degrees of abduction; Increasing the arm by more than 30 degrees is usually caused by deltooid.

Supraspinatus muscles can lead to pain and weakness when the arms are raised from the body. Another symptom that may be experienced is pain when pressure is applied to the front of the upper arm. Symptoms of this nature may be caused by a tears of muscle supraspinatus do not delay tendons supraspinatus or muscle itself. Such injuries may be caused by excessive muscles, especially excessive force, while the arm is raised above the shoulder or a fall that causes physical trauma on the shoulder. Treatment may include the use of anti -inflammatory drugs and specially designed Supraspinatus muscle exercises to rehabilitate muscle.
